RIZ TRANSMITTERS 10-100 SW

GENERAL DESCRIPTION

SW INVERTED CONE ANTENNAS RIZ 10-100 SW

These Vertically Polarized Single Mast Inverted Cone Antennas are developed in order to cover needs for simple and frequency extremely wide SW antennas, applicable in mobile and/or stationary service. Each antenna comprises a single base insulated tower, 25m height, supporting a curtain of radiators that diverge from the top of the tower, and converge again at the bottom of the tower, and the grounding screen. The inverted cone radiator wires are electrically connected to a continuous circulating catenary.

This catenary is held out from the tower by twelve insulated guys.

The tower and lower apex of the cone are connected to the upper base plate which is insulated from the ground by the base insulator. The tower and radiating cone are directly feed through the 50 ohms RF coaxial transmission line without additional matching. These antennas have an omniazimuthal radiation pattern and provide both ground wave and sky wave service over SW broadcast bands.

The antenna can be directly connected to a 50 ohms RF coaxial transmission line.
